MACHINE FOR USE IN MAKING BOXES 0R CBATES.

Application filed March 24, 1921. Serial No. 455,301.

To all whom it may concern:

Be it known that I, Osononn O. THOMP- SON, a citizen of the United States, and a resident of the borough of Rockaway, in the county of Morris and State of New Jersey,

have invented a new and useful Improvement in Machines for Use in Making Boxes or 'Grates, of which the following is a specification.

The invention relates to machines for use in fastening heads, ends or the like to boxes, crates or the like, such machines being sometimes referred to as end stapling machines.

Among other objects, the invention 15 1ntended to provide a machine of the class described, having improved means for controlling or positioning the box or crate parts during fastener driving operations.

One illustrative form 0 machine embodying the invention is shown in the accompanying drawings in which:

Fig. 1 is a general side elevation view of a machine embodying the invention, showing a crate partly broken away in position to be operated'upon. I

Fig. 10 is a perspective view of the stationary body member of the work-controlling means.

Fig. 11 is a perspective view of the movable member 0 thework-controlling means.

Fig. 12 is a perspective view of a portion of a wire bound crate showing an end section fastened to the cleatsof side sections.

One illustrative type of crate upon which the machine is designed to o erate is partly illustrated in Fig. 12. T e crate there shown is commonly referred to as a sectional wire bound crate and consists of four separate sections of slatted side material a and cleats I) connected together in foldable relationship by binding wires 0 stapled thereto, and head or end sections d stapled to the cleats b of one or more side sections by staples e as illustrated. In ractice the materials for the four sides of tlie crate are usually assembled and secured together in a crateblank machine which connects the four sides of the crate with wires producing) what is commonly referred to as a crate lank. The blank thus formed is artially folded about the heads or en s d as shown in Fig. 12, and the heads or ends are then stapled to cleats b of side sections a of the crate. The illustrative machine is designed for use in performing. this last operation, that is for use in fastening the end section d to cleats b of one or more side sections and is designed to o erate within the crate, close to the sides t ereof and in the corners and to drive staples through the head or end (1 into or through cleats b.

As illustrated in Fig. l the invention is embodied in an end stapling machine of the type disclosed in the patent to Thompson No. 1,295,237 issued February 25, 1919, consisting generally of staple forming and driving mechanisms, and clamping or clinching mechanism to co-operate therewith during staple driving operations. It will be understood, however, that the invention is not limited to the particular end sta ling machine illustrated but may be embodied in other types of which there are several.

The illustrative machine is supported by the frame 1 which carries arms 2 and 3 having an opening therebetween to permit the insertion of a cleat of a box or crate and an end or head as shown in Fig. 1. Arm 2 whichcarries the staple driving mechanism is formed with a narrow nose adaptedto enter the box or crate, close to the sides thereof and in the corners and arm 3 carries the clincher mechanism for clamping the box or crate parts in position during the staple driving oper tion and for clinching any staples that may be driven through the materials. Staples 4 are formed from wire 5 by staple forming mechanism (not shown) located at the rear of the machine and are fed forward to the nose of arm 2 with their points upstanding in the manner illustrated in said patent to Thompson above referred to. From the nose of arm 2 the staples are driven upward through the head or end (1 into the cleats b of the box or crate.

The mechanisms for forming, feeding and driving the staples and the clincher mechanism need not be shown or described in detail as said mechanisms are fully shown and described in the patent to Thompson above referred to.

In 0 eration the head or end d is placed upon the upper surface of the lower arm 2, and the three sides of the box or crate are wrapped about the head or end with the cleats b above the end d. Staples are then driven at intervals through the head or end cl into the cleats b of side sections a of the box or crate, the work being shifted by the operator after each stapling operation.

To increase the holding power of the staples it is desirable to drive them along y the longitudinal center line of the cleats.

As shown in Figs. 4, 5 and. 6 therefore, the driving point a: s located at such a distance relative to the nose of the arm 2 that when a box or crate is placed upon said arm the side material of the box or crate will not prevent the proper positioning of the cleat over the driving point.

Heretofore, as in the machine of the Thompson patent above referred to, the work was positioned for a stapling'operation by the nose of the stapling arm 2 which contacted with or engaged the side material of the box as it .was pressed against the nose by the operator and as the box was shifted for each stapling operation the nose of the stapling arm dragged along the inner surface of the side material thus positioning the driver relative thereto and relative to the cleat. Such work-controlling means is effectual for positioning a box or other packing case having in effect integral or continuous side material. It has been found in practice, however, that when a crate or other packing case having openings in the side material is being operated upon that the nose of the stapling in such openings or partially passes through them thus improperly positioning the work, causing inaccurate positioning of staples and otherwise delaying the stapling operation.

In the illustrative machine, work-controlling means for properly positioning the materials for the fastening operation re rdless of o nings in the sides of the pac ge is provi ed.

As illustrated said means takes the form arm often catches of an attachment to the under side of the nose of upper arm 3. It will be understood,

designed to position or gauge the work for a stapling operation from the cleat b of the illustrated crate, which as shown in Fig. 12, has no openings into which the workcontrolling means may enter as the work is shifted for successive operations. Said work-controlling means is also designed to position the longitudinal center line of the cleat directly above the staple driver regardless of the angle at which the cleat is held relative to the longitudinal center line of the stapling arm 2.

Referring to Figs. 8 to 11 the illustrative work-controlling means comprises a positioning member 6 movable in a semi-c1rcu lar path about the driving point a as a center and adapted to engage a cleat of the illustrative crate and soposition the parts relative to the staple drivlng point and the nose of the stapling arm that the cleat will be properly positioned over the staple drivmg point, and openings in the side material of t e crate will be held clear of engagement with the nose of lower arm 2. I

As shown in Figs. 8 to 11 the positioning member 6 is carried by a semi-circular memher 7 which is adapted to rotate in semicircular rabbeted groove 8 formedin a body member 9 bolted tothe lower surface of the nose of the uuper arm 3 by means of screws 10. The circular groove 8 in which the member 7 rotates is positioned about the driving point a; as a center so that member 6 in whatever position it may be relative to the longitudinal center line of the arm 2 will always be at the same distance relative to the stapling point a: and the member 6 is so located relative to the driving point that when a cleat is pressed against said member the longitudinal center line ofthe cleat will be positioned directly above the driving point a: and so long as the cleat is pressed against member 6 its longitudinal center line will always be directly above the driving point regardless of the shifting of the cleat or the angle at which it is held relative to the longitudinal center line of the stapling arm.

As shown in Figs. 4, 5 and 6 the crate is shifted over the drivin point for each succeeding stapling operation and in stapling the end tocleats of successive adjacent sides said cleats are held at various angles to the longitudinal center line of the stapling arm. Member 6, however, accommodates itself to this shifting of the work by moving about the driving point a: maintaining, at all times, the same relative distance therefrom and always correctly posithe nose of the machine. Fig. reverse of Fig. 5 showing the work-convarious machines embodying crates functioning to fasten hea show the manner. in which the member 6 is rotated about the driving point a: by pressure of a cleat thereagainst.

' In Fig. 4 the cleat being operated upon isfh'eld. at'approximately ,a right angle to the longitudinal center line of the arm 2 and in this position the member 6 assumes a position about midway between the extremities of its semi-circular path of travel and properlypositions the cleat above the driving point a; while holdingdhe side material clear of engagement with the nose of the stapling arm. In Fig. 5 the cleat being operated upon is held approximately parallel with the tapered side of the stapling arm and the member 6 has been shifted to one extreme of its semi-circular paths In this position the same relationship between the riving point and the longitudinal center line of the cleat-is maintained and the side material is held free of engagement with 6 is the trolling member at the other extreme of its path of movement. Figs. 4, 5 and 6 respectively show cleats being operated upon at three different angles to the longitudinal center line of the stapling arm. The cleats when shifted are often held at angles different from those shown particularly when staples are being driven into the cornersof the box or crate. means, however, will accommodate itself to any angle at which the cleat being operated upon is held relative Y to the longitudinal center line of the stapling arm, and regard less of the angle at which the cleat is held relative to the longitudinal center line of the stapling arm the longitudinal center line of the cleat will always be correctly positioneddirectly above the stapling point and the nose of the stapling arm will be held clear of openings inthe side material. I
